Primary: New Hampshire has a mostly closed primary system, in which the selection of a party's candidates in an election is limited to registered party members. In New Hampshire, however, Independent voters may choose which party's primary to vote in.

Voter registration: Voters were required to register to vote in the primary by September 4, or at the polls on election day. For the general election, the voter registration deadline was October 27, or at the polls on election day.[1]

Primary competitiveness

The national average is 54.31%.

Two U.S. House incumbents are seeking re-election in New Hampshire in 2012. 2 of those 2 (100%) faced a primary challenger. Nationwide, 200 out of the 386 incumbents seeking re-election faced a primary challenger (51.81%).
